My name is Rahul Dowlath and I am studying the design of buildings, at the University of Cape Town.
As part of my postgraduate studies to become a professional architect I am doing research on public buildings and space, youth development agencies and sports and recreation facilities. I would like to ask you some questions about this to help me with my research.
The questions I ask are only for education and research and do not directly benefit you or your community; you will not be compensated for your participation.
I must be careful not to raise expectations, as no improvement to any facilities will result from the interview.
The information which I am gathering will be used in my course and exams, and may also be published in academic journals or exhibitions.
I would like to record the interview, if you agree.
You have a right to refuse to answer any questions. If you want to end the interview at any point you are free to do so.

INTERVIEW WITH TOWN-PLANNER:
» When was Heideveld formed? / What was it like growing up in the area?
» How was it planned? What planning strategies were used?
» How has it grown or developed over time?
» What is the relationship with other surrounding suburbs (Gugulethu/Phillipi/Mannenberg…) / tensions, networks?
» Youth development: are there any after-school programmes?
» Schools: how does the community interact with them? are they used as spaces for hired activity in downtime (evenings/weekends/holidays)?
» Presence of schools in neighborhood: safety, lockdown? vandalism?
» Where do kids go after-school?
Gangsterism
» What is the spatial effect of gangs are operating in the area? Do they create controlled territories that prevent people from freely moving about the suburb?
» Tensions with law enforcement? Have there been any major incidents?
» How do these gangs affect schools / youth?
Are youth succumbing to joining them, and do afterschool/lack of afterschool programmes have anything to do with this?
» Community development: is there a top-down approach from the city towards development (long term growth plans etc), or is there a drive from the community towards community building/development?
» New bridge across train lines: any background to this? Reasons for it being placed across from large piece of abandoned land?
» Site: reason behind the empty pockets of land?
Are they a relic of apartheid planning strategies?
» Site: is there any plan for this area? For the pockets of empty space?
» Site: roads built to suggest some sort of stalled development? What was intended for that
+ And data pertaining to area that might be helpful + Thank you
» Where do your students come from?
(Heideveld/Gugulethu…?)
» When does school open and close? What time do kids start arriving?
» How do kids get to school? (Walk/public transport?)
» How is security managed at the school – what kinds of barriers/boundaries are used? Is there any kind of surveillance?
» Are there any afterschool activities run by the school?
» Are there any afterschool activities run by third-parties that make use of the school’s facilities?
(E.g. does MOD-C operate here?)
» What are the main sports played?
» Are there any inter-school connections with sport (inter-school matches?) And if so, with which schools?
» Have there been any safety incidents? Issues of crime?
» Are the school’s facilities hired-out/used during off-peak times by the community for functions/
» Are any facilities/spaces shared between this school and Willows/Heideveld High? on to join the club and move through its ranks?

The following images are from the journal IMIESA by the City of Cape Town that shows the various design options explored by the engineers who designed the Heideveld Pedestrian Bridge.
The bridge was built on an existing desire line that cut across the train lines. According to the article, 'previously, there was no pedestrian bridge north of Heideveld Station that the public could use without a railway ticket.' (City of Cape Town, 2011)
Furthermore, many school children make this crossing daily from New Rest in Gugulethu to the two schools in the Heideveld precinct (Willows Primary and Heideveld High). The woonerf concept guided the design, which includes a large mound (or berm) that rises on the Heideveld site to meet the height of the steel pedestrian bridge.

the various design iterations. They explore issues of solar radiation on the proposed roof geometries, and basic CFD wind simulation using the Autodesk Flow Design environment to understand how wind moves through and around the building.
Wind speeds for the CFD tests were obtained from local weather data for Cape Town and were set to 7m.s-1
Solar radiation used the local EPW weather file from Ladybug, the environmental analysis tool in the Grasshopper environment where the solar analysis took place.
CFD test on an early concept of the current wrap-around roof design (iteration 4 on p89). Orange indicates an increase in velocity around the top southern edge of the roof.
Solar radiation analysis on test geometry (01 – with no roof)
Solar radiation analysis on test geometry (02 – with multiple butterfly roofs)
Solar radiation analysis on test geometry (03 – with concrete shell roof) Solar radiation analysis was mainly used to visualise the
effect of solar radiation on the building's northern face, and to see how different roof options affected solar

During the peak usage times (see table above), how much water is being used by the water savings if all showerheads in the changerooms use the specified low-flow system
ENERGY
Water storage required = 1240ℓ
Therefore, how many kWh are required to heat this stored water? (through 10ºC?) E = m x specific heat capacity x ∆temperature
= 1240 x 4187 x 10ºC
(shc of water = 4187/kg/ºC)
= 51 918 800 J
= 14,42 kWh
Therefore, a solar geyser system with heating capacity for 14,42 kWh is required to heat 1240ℓ for use in the change rooms.
In responding to the current water & energy crisis facing the City of Cape Town, this sustainability analysis guided the water and energy strategy for the project.
It is reasoned that the club's change-rooms &
